Research And Development Of Environment Monitoring System For Solar Greenhouse Based On Internet Of Things Technology

As the basic industry for national economic development,agriculture has a bearing on the people's basic livelihood and the long-term peace and stability of the country.There are more people and less land resources in China,we should greatly develop modern agriculture.As an important part of agriculture in modern facilities,the greenhouse breaks the seasonal and geographical restrictions of traditional agriculture,creates an environment suitable for growing crops,and realizes the goal of increasing production and increasing income.This project comes from Inner Mongolia Autonomous Region of science and technology innovation guide reward fund project "facilities agriculture key equipment and development and industrialization demonstration based on IoT".Collaborated with the Inner Mongolia Autonomous Region Institute of Biotechnology,developed a set of low-cost,practical solar greenhouse environmental monitoring system based on the Internet of Things technology.The system realizes real-time monitoring of environmental parameters,remote control of equipment and scientific management of greenhouses.Based on the investigation of the characteristics and application environment of the solar greenhouse environmental monitoring system,this paper has carried out a detailed feasibility analysis and demand analysis,based on the basic framework of agricultural Internet of things,combined with sensor technology,communication technology,cross-platform application development technology of Qt,hybrid mobile application development technology,put forward the overall design of greenhouse environmental monitoring system.The system includes a lower computer system consisting of sensors,transmitters,controllers,collectors,and a host computer system consisting of a Qt-based device configuration utility and a local management system,an Ionic2-based smart phone APP,and a Tlink-based cloud platform.The lower computer system completed the selection of sensor,controller,the design of hardware,software,appearance and communication protocol for transmitter,collector,gateway.The host computer system completed the design of application based on Qt and the APP based on Ionic2,communication with cloud platform of Tlink.From May 2017 to November 2017,the system is deployed in five greenhouses of ecological picking park in the Wuchuan County of Hohhot City,for a six-month field test.The test results show that the system can operate stably and reliably for a long time in a solar greenhouse environment and simplify the daily management of solar greenhouse.
